DESCRIPTION

IO::File
inherits from IO::Handle
and IO::Seekable
. It extends
these classes with methods that are specific to file handles.

CONSTRUCTOR

new ( FILENAME [,MODE [,PERMS]] )

Creates an IO::File
. If it receives any parameters, they are passed to
the method open; if the open fails, the object is destroyed. Otherwise,
it is returned to the caller.

new_tmpfile

Creates an IO::File
opened for read/write on a newly created temporary
file. On systems where this is possible, the temporary file is anonymous
(i.e. it is unlinked after creation, but held open). If the temporary
file cannot be created or opened, the IO::File
object is destroyed.
Otherwise, it is returned to the caller.

METHODS

open( FILENAME [,MODE [,PERMS]] )

open( FILENAME, IOLAYERS )

open accepts one, two or three parameters. With one parameter,
it is just a front end for the built-in open function. With two or three
parameters, the first parameter is a filename that may include
whitespace or other special characters, and the second parameter is
the open mode, optionally followed by a file permission value.

binmode accepts one optional parameter, which is the layer to be
passed on to the binmode call.

NOTE

Some operating systems may perform IO::File::new()
or IO::File::open()
on a directory without errors. This behavior is not portable and not
suggested for use. Using opendir() and readdir() or IO::Dir
are
suggested instead.
